Error when buil GND plane.

When i buil a GND plane and have some error but i don't know why, please help me.

1. The first, i buil GND plane with size dimention same with size of board -> have a net (not GND) connect with GND plane.

2. When i change size dimention of GND plane -> OK.

Thank you for your inquiry.
I apologize for the delay in replying to you.

In regard to the issue that the GND plane is connected to the object with different net,
we have not yet reproduced the symptom although we are investigating it.

Then, I would like to confirm one thing but,
would you let me know the Quadcept version you are using now?
The version can be confirmed by clicking [Settings] -> [Version Information].

Also, if possible, would you send the data having the problem to
the following mail address for the investigation?
